This document appears to be a technical catalog or specification sheet related to the "Zen" product line from Fontanot, likely concerning stair components or modular parts given the references to measurements and article numbers.

Product Identification

The document lists multiple article numbers (e.g., Art. K70005000, Art. K70004000, Art. K70003000, etc.) which likely correspond to different components or models within the Zen series. These article numbers are grouped and repeated, suggesting a range of related products.

Dimensional Specifications

Several ranges of measurements are provided, mostly in centimeters, such as "21.2 ÷ 25.7 cm", "23.1 ÷ 28.0 cm", "25.0 ÷ 30.4 cm", "26.9 ÷ 32.7 cm", and "28.8 ÷ 35.1 cm". These likely represent adjustable or variable dimensions for the products, possibly indicating height, width, or depth ranges.

Additional fixed measurements such as 61 cm, 90 cm, 100 cm, 109 cm, 112 cm, 118 cm, 127 cm, 128 cm, 139 cm, 140 cm, and 150 cm are also mentioned, which may correspond to standard sizes or installation parameters.

Layout and Numbering

The document includes sequences of numbers from 1 to 15, sometimes repeated or grouped, which might indicate steps, component positions, or assembly stages. The presence of these numbers alongside measurements suggests a modular or stepwise assembly process.

Source and Identification

The footer references the website www.fontanot.it and includes a print code "STAMPA DIC. 2014 - cod. 066784000_1", indicating the document was printed or produced in December 2014.

Summary of Critical Information

• Product Range: Multiple article numbers indicating a broad product line.
• Adjustable Dimensions: Variable ranges in centimeters for key product parameters.
• Standard Sizes: Fixed measurements likely used for installation or compatibility.
• Assembly Indicators: Number sequences suggesting modular assembly or component identification.
• Source: Fontanot official website and print date for reference.

Overall, the document serves as a technical reference for the Zen product series, focusing on product codes and dimensional data essential for selection, installation, or assembly. However, due to the fragmented nature of the text and absence of explicit procedural or normative content, the summary is limited to identification and dimensional specifications.
